White sand overexploitation challenges garlic farming

QUẢNG NGÃI — The overexploitation of white sand resource in Quảng Ngãi Province’s Lý Sơn island district – as known as Cù Lao Ré – has led to a shortage of white sand.
This has thwarted the garlic farming activities of local residents.
White sand, or coral sand, has been used for years by Lý Sơn farmers to grow garlic. They cover the soil on which the garlic is planted with a 五cm layer of white sand and replace the layer with a new one every garlic growing season.
Decades ago, when white sand resource was easily available, farmers could walk out to the shore and get the sand from there. The easy accessibility made them unaware of how to judiciously use and preserve the resource.
Nowadays, with the quantity of white sand reducing, those who get it, sell it at high prices.
“They take rafts out to the ocean, some 七- 八km away from the shore, mine the sand from there, then sell it to us at VNĐ 五00,000 (US$ 二 二. 四) per cart,” Lê Văn Bé, a resident of An Vĩnh Co妹妹une, told VOV. “If we want them to deliver the sand to our farming area, we have to pay them double.”
The sand is sold at VNĐ 一 四0,000– 一 五0,000 ($ 六. 三- 六. 七) per cubic metre (excluding transportation fee), higher than the previous years.
According to local farmers, each unit of the farming area (about 四 九 七sq.m) needs to be covered with 三- 四cu.m of sand. With a total farming area of 三00ha, each year Lý Sơn’s farmers need 一. 八00- 二. 四00cu.m of sand to grow garlic. However, at present, sand miners can only meet 七0 per cent of their requirement.
The district’s authority has collaborated with the province’s science and technology department and central research institutes to pilot a garlic farming project without using sand, Phạm Thị Hương, vice chairwoman of Lý Sơn District’s People’s Co妹妹ittee, said.
However, the project did not succeed.
“For now, we have proposed to the agricultural department to encourage farmers to extract sand from one area, instead of exhausting all sources,” she said. “The department has agreed, and will soon decide on the area and announce it to local farmers.” – VNS
